Gaming desktop with GTX 1060 3GB

The HP OMEN Obelisk 875 is a gaming desktop powered by an Intel Core i7-8700 6-core processor and NVIDIA GeForce GTX 1060 graphics with 3GB GDDR5 memory. It includes 16GB DDR4 2666MHz RAM and dual storage with a 256GB NVMe SSD plus 1TB HDD. Windows 10 Home is pre-installed.

Suits 1080p gaming and easy upgrades

This system suits players targeting 1080p resolution who want a tool-less chassis for straightforward component swaps. The 500W power supply supports the included graphics card. Buyers who need more video memory for higher textures or modern ray-traced titles should look elsewhere.

GTX 1060 3GB GDDR5 graphics card

The dedicated NVIDIA GeForce GTX 1060 with 3GB GDDR5 video memory determines which games run smoothly at desired settings. It provides HDMI, DisplayPort and DVI outputs for multiple displays. If your workflow demands more than 3GB VRAM, this is not the right part.

Questions about this item

How do I open the OMEN Obelisk 875 case to add an NVMe drive, and what step is often missed?

The side panel lifts off without tools; the step people miss is seating the M.2 screw fully so the 256GB NVMe or added drive makes proper contact.

Which component will likely need replacement first if I push the GTX 1060 3GB in modern titles?

The 3GB GDDR5 video memory fills before the GPU core saturates, so texture quality drops and stutter appears — adding system RAM helps but cannot expand VRAM.

What thermal limit appears first during long sessions with the 500W supply and i7-8700?

The 500W power supply reaches its sustained-output ceiling before the CPU hits its 4.6GHz turbo, causing the system to throttle clocks to stay within the power envelope.
